Estimation of Tensile Properties of Pipe Bends Manufactured by Cold-Bending

Transactions of the Korean Society of Mechanical Engineers A, 2012
In this study, tensile tests were performed on specimens that simulated the cold-bending and heat-treatment of pipe bends to understand the mechanical properties of pipe bends manufactured by cold-bending followed by heat-treatment for relieving residual stress.

Bend properties of sapphire fibers at elevated temperatures I: Bend survivability

Materials Science and Engineering: A, 1995
Abstract The effect of temperature on the bend radius that a c -axis-oriented sapphire fiber can withstand was determined for fibers of various diameter. Bend stress rupture tests were performed for times of 1–100 h and temperatures of 300–1700 °C. Fibers would survive the bend test undeformed, would fracture or would deform.

Microstructure and mechanical properties of the start bending point for X90 bend

Materials Science and Technology, 2023
The effect of the hot induction bending process on the microstructure and mechanical properties of the start bending point for high-strength bends was investigated. Acicular ferrite (AF) is found to be absent in the microstructure of the start bending point.

Mechanical Properties of Cold Bend Pipes

Journal of Pressure Vessel Technology, 2006
Cold bends are frequently required in energy pipelines in order to change the vertical and horizontal orientations of the pipeline route. They are produced by plastically bending a pipe joint in a cold bending machine by creating a series of uniformly spaced incremental bends. This procedure acts to reduce the moment capacity and buckling strain of the

Time-Dependent Bending Properties of Lumber

Journal of Testing and Evaluation, 1996
Abstract Research related to structural stressed-skin panels (SSP) and their component parts has been ongoing at Chalmers University of Technology. In recent years, attention has been focused on SSP with lumber webs and sheet metal and chipboard panels as tension and compression flanges, respectively.

Bending Properties of Carbon Nanotubes Encapsulating Solid Nanowires

Journal of Nanoscience and Nanotechnology, 2002
Using empirical potentials and atomistic simulations, we model three-point bend tests of single-walled carbon nanotubes encapsulating metal nanowires. The presence of a metal nanowire inside the nanotube greatly suppresses the tube-buckling instability.

Orthotropic Bending Properties of Fiberboard

1975
Abstract : An experimental procedure for the determination of the orthotropic bending stiffness of fiberboard is described, including the loading apparatus, strain gauges used, recording equipment and data reduction procedure. Results obtained using the described procedure are presented for V3C fiberboard.

BENDING PROPERTIES OF LAMINATED-LUMBER GIRDERS

Applied Engineering in Agriculture, 2000
Twenty-seven girders were “built up” from dimension lumber and tested to failure in bending. Each girder was 7.9 m (26 ft) in length and contained three layers, with each of these layers comprised of stacked 38 ×140 and 38 × 235 mm (nominal 2 ×6 and 2 ×10 in.) members. Nails were used to join individual layers in 10 of the assemblies.

Electromechanical Properties of Composite Bending-Type Transducers

Japanese Journal of Applied Physics, 1995
A composite bending-type transducer is proposed for the purpose of measuring the elastic compliance constant of nonpiezoelectric material at rather low frequencies. It consists of two thin plates with different thicknesses, bonded together, of which one is piezoelectric and the other is nonpiezoelectric.

Flexible film waveguides with excellent bending properties

SPIE Proceedings, 2008
We have developed a film waveguide which has excellent bending properties. The waveguide can be fabricated by existing exposure/development processes and facilities with a core and a cladding dry film. Based on the bending loss simulation results, we fabricated the film waveguides of which the core-cladding index difference (relative index ...
